Great discussion guys. Let's not forget that Harrell, Bill Thomas, and their work with Nickey started the concept, and, made it work. Not that Yenko & Motion wouldn't have done it anyway, but, the Stefani brothers at Nickey took the concept to market, and, did a great job of marketing these conversion cars before anyone else.
As far as who was the first or the best, however, I love 'em all. Some prefer the "factory hot rod" COPO type cars, some like the dealer built conversion cars, which typically were built for more performance. They're all an important part of the Supercar legend, and, have a unique place in musclecar history.
